We travelled up and down the Bruce last year, These are some of the free camps we stayed at.....Calliope River crossing....St Lawerence....Clairview..Gunthalunga...Home Hill... Balgal Beach.. Hull Heads.. Babinda Boulders... There are many more these were just some of our favourites....hope you have a great trip....
im guessing glasshouse mountains is not too far from brisbane so wouldnt want to stop that early however there is a little area people pull up in beside the shops as you come into glasshouse you keep veering right and there is a info centre keep going a little and you can see a small area where the cars park , ive seen people sleeping in there before.
Also there is another as far as i know just before glasshouse mountains towards beerburrum jc and kiwi as stayed there after they left here due to traffic congestion on there way home.
